Hello ! I had the same issue. I solved it by adding two more lines in the file bridge.py :
class Bridge(object):
""" MAVLink bridge
Attributes:
┊ conn (TYPE): MAVLink connection
┊ data (dict): Deal with all data
"""
def __init__(self, device='udpin:192.168.2.1:14550', baudrate=115200):
┊ """
┊ Args:
┊ ┊ device (str, optional): Input device
┊ ┊ ┊ https://ardupilot.github.io/MAVProxy/html/getting_started/starting.html#master
┊ ┊ baudrate (int, optional): Baudrate for serial communication
┊ """
┊ self.conn = mavutil.mavlink_connection(device, baud=baudrate)
#--------Lines to initiate mavlink data stream-----------
┊ self.conn.wait_heartbeat()
┊ self.conn.mav.request_data_stream_send(self.conn.target_system, self.conn.target_component, mavutil.mavlink.MAV_DATA_STREAM_ALL,4, 1)
#---------------------------
┊ self.data = {}
.....
If you want more information about the parameters of the request_data_stream_send method you can check https://mavlink.io/en/mavgen_python/#listen to see how to use pymavlink and https://mavlink.io/en/messages/common.html for the parameters (e.g. MAV_DATA_STREAM_ALL)
Otherwise, if you start QGroundControl at the same time or before launching the bluerov2 node, it works for me.
BR, Nathan
